ADUM1200WURZ35

Overview

The ADUM1200WURZ35 is a dual-channel digital isolator utilizing iCoupler magnetic coupling technology. It provides 2500Vrms isolation with unidirectional signal transmission across two channels. The device supports data rates up to 25Mbps and operates on a supply voltage range of 3V to 5.5V. Key electrical parameters include a maximum propagation delay of 45ns, typical rise and fall times of 2.5ns, and a minimum common-mode transient immunity of 25kV/µs. It is housed in an 8-lead narrow body SOIC package.
